Description
Этилат натри (СНзСН2ОМа) широко примен етс в фармацевтической промышленности в качестве конденсирующего агента при производстве , например, витамина В , пирамидона, антипирена, анальгина, люминала, верон1ала и т. п.Sodium ethoxide (CH3CH2OMa) is widely used in the pharmaceutical industry as a condensing agent in the production of, for example, vitamin B, pyramidone, flame retardant, analgin, luminal, verontal and the like.
Этилат натри получают из абсолютного этилового спирта и металлического натри . Это производство вл етс огне- и взрывоопасным.Sodium ethoxide is obtained from absolute ethyl alcohol and metallic sodium. This production is flammable and explosive.
Этилат натри можно также получить из спирта и ш,елочи. Образующуюс в результате реакции воду удал ют методом ректификации азеотропной смеси, использу бензол в качестве вспомогательной жидкости . Этот способ не нашел промышленного применени вследствие сложного аппаратурного оформлени процесса ректификации и плохого качества этилата.Sodium ethylate can also be obtained from alcohol and w, herpes. The water resulting from the reaction is removed by azeotropic rectification using benzene as the auxiliary liquid. This method has not found industrial application due to the complex instrumentation of the rectification process and the poor quality of ethylate.
В предлагаемом способе процесс получени этилата натри из спирта и едкого натра очень оригинально оформлен в двух аппаратах с холодильником дл непрерывного обезвоживани спирта и возврата его в реактор дл получени этилата натри ,. В качестве дегидратирующего вещества используетс окись кальци .In the proposed method, the process of obtaining sodium ethylate from alcohol and caustic soda is very original in two apparatuses with a refrigerator for continuous dehydration of alcohol and returning it to the reactor to obtain sodium ethoxide,. Calcium oxide is used as a dehydrating agent.
На чертеже схематически изображена установка дл осуществлени предлагаемого способа.The drawing shows schematically an installation for carrying out the proposed method.
Трубка 1, вставленна через пробку в колбу А, изолирована в верхней части асбестовым шнуром и соединена с холодильником, нижн трубка которого в свою очередь соедин етс с трубкой 2, доход щей почти до дна колбы Б. Через пробку колбы Б проходит трубка 3, соедин юща верхнюю часть этой колбы с нижней частью колбы А. Обе колбы имеют обогрев.The tube 1, inserted through the stopper into the flask A, is insulated in the upper part with an asbestos cord and is connected to a cooler, the lower tube of which in turn is connected to the tube 2, which reaches almost to the bottom of the flask B. The upper part of this bulb is the lower part of bulb A. Both flasks are heated.
В колбу А (емкостью 500 мл) загружают 200 мл 95Vo-Horo этилового спирта и 30 г 95«/о-ного едкого натра. В колбу Б (емкостью 75 мл) заливают 300 мл 957о-ного спирта и 200 г негащеной извести.200 ml of 95Vo-Horo ethyl alcohol and 30 g of 95 “/ of caustic soda are charged to flask A (with a capacity of 500 ml). In flask B (75 ml capacity) pour 300 ml of 957-oh alcohol and 200 g of quick lime.
После загрузки компонентов колбы нагревают до кипени спирта. Пары спирта и воды из колбы А по трубке 1 поступают в холодильник 4, конденсат по трубке 2 стекает в нижнюю часть колбы Б и непосредственно соприкасаетс с известью, котора отнимает воду от влажAfter loading the components, the flasks are heated to boil the alcohol. Alcohol and water vapors from flask A through pipe 1 enter refrigerator 4, and condensate through pipe 2 flows into the lower part of flask B and comes in direct contact with lime, which takes water away from moisture.
